PRINTING-TELEGRAPH.

'SPECIFICATION forming part of Letters Patent No. 299,664, dated June 3, 1884.

I Application tiled June 6, 1883. (No model.)

To aZZ- whom, it may concern.:

Be it known that I, WILLIAM J. McGA'Us- LAM), of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented van Improvement in Printing-Telegraphs, of which the following is a specification.

My invention has reference to printing-telegraphs; and it consists in certain improvements, fully set forth in the following specication, and shown in the accompanying drawings, which form part thereof. v

The obj ect of my invention is to so construct a printing-telegraph that it may be worked with far greater rapidity and accuracy than has heretofore been possible with machines in use. Y

In the drawings, Figure l is a sectional elevation of my improved printing -telegraph. 2o Fig. 2 is a plan of same. Fig. 31s an enlarged detached view of the mechanism for operating the type-wheel, and, Fig. 4 shows the typewheel and its slotted screw.

A is the base. v y

B is the type-wheel, and is secured on shaft C, journaled in suitable bearings or support, D. This shaft C carries a spur-wheel, E, and a unison stop-pin, R. The pinion E', secured to the shaft e, which is carried by a bearing, 3o f, meshes with said spur-wheel E and rotates the same. Shaft e is provided with a crank, F', and bar F, set substantially at rightgangles to said crank, and against which a spring, H, constantly presses. Crank F' is connected to an arm, G, 'pivoted toa standard, g, by a link, F2. The arm G is vibrated by a rod, I, and armature I', which works between polarized electro-magnets J J',which alternately change their polarity, so that when one is north the other is south, and vice versa. The armature may be counterbalanced by a spring, G'. The transmitting-instrument may be of any desired construction 5 but for simplicity the following is shown: A vibrating hammer, K', strikes alternately the contact-blocks 7c', respectively connected to the two poles of the battery K2, so that a current of either polarity may be transmitted over the linek, through electro-magnets' .I J', into ground at 7c. The

5o type-wheel B may be constructed in any desired manner, but is preferably made with the letters and iigures arranged circumferentially about the said type-wheel and in two separate parallel frames, the figures being arranged f opposite the spaces between the letters, so that each revolution of the pinion E' will cause, if desired, two letters and two gures to be printed; hence each reciprocation of the armature I' moves the type-wheel a space covered by two letters and two gures. f

L is the printing-frame, and is adapted to move horizontally in guides Z. It is provided with an armature, L2, arranged before magnets M M', coupled in pairs and receiving a current. from an eXtra line-wire, N, over which a strong current may be sent by battery P upon closing key N'. The printing-frame, upon being drawn toward the press-magnets, compresses a spring, L, encircling rod L3, and the throw or movement of said frame may be 7o regulated by nuts L5. The paper T is wound upon the usual reel,V, supported by the standards U, andpasses under bars Z', over printing'- block L', under another bar, m', and inally over aplate, Z", forming part of the press-frame. '75

S is a pivoted arm 'pointed at the bottom, carried by press-frame and pressed upon the paper by spring s.

S' is another pivoted arm similar to that just described, but is pivoted to the station- 8o ary support g or frame of the machine, and is pressed upon the paper by a spring, s. The unison consists of two IieXible conductingarms, R', insulated from each `other, respectively connected by wires r r' with the line 85 K on each side of the type-wheel magnets J J', and are raised or lowered within range of pin R2 by armature O and unison-magnet O in the press-magnet circuit N.

B is a stationary screen, having a slot, b, 9o therein to prevent the printing of more than one letter or figure at one time.

, The operation is as follows: Currents of electricity of alternate opposite polarity are transmitted down the line K, causing the armature v I', rod I, and arm Gto vibrate rapidly. This causes the pinion E' to rotate rapidly, the crank F' being carried over the dead-centers by the bar F and spring H, (see Fig. 3,) thereby rapidly rotating spur-wheel E and type-wheel B. roo

Vhen the ydesired letter' is reached, the lever K is arrested. Key N is then closed, causing the current from battery B to pass over line N, then to divide and pass partly over each magnet M M. rIhis causes the armature L2 to be attracted, compressing spring If, reciprocati n g the lness-frame L, and causing the paper to be pressed against the type-wheel, causing the impression from the desired letter to take place through the slot b in the perfo rated shield or screen Il. The reciprocation of the press-frame and the action of the pivoted arms S S cause the paper to be intermittently fed through the machine. As a space between the figures is always in line with the letters, nothing but a letter will print through the slot in the shield. XV hen print ing a letter, the crank Il" is always on the deadcenter, and the arm F puts the spring II under tension, asindieated in dotted line Fig. 3; hencewith every semi-revolution a letter may be printed. If it is desired to print a figure, the type-wheel is worked around until the letter immediately before t-he desired. figure is reached, and then upon breakingthe line-current in wire K the crank Ff assumes the position shown in full lines, Fig. 3, and which, by the proper relative sizes of' the wheels E and E', causes a figure to come before the opening in the shield, and now upon printing` a figure would be printed, hence two figures might be printed for every evolution of the pinion E. By this construction of mechanism I am enabled in practice to almost double the speed of the printing-telegraphs now in use, and which is the main object of my invention. By dividing the current over two press-magnets I am enabled to greatly increase the power from a given battery, and thereby with small magnets ain enabled to print more positively and perfectly. If it is desired to bring the instrument to unison, I close a key, N2, and put a small current to line N, which current is insufficient to operate the press-frame, but is amply sufficient to operate the armature O', and throw the spring-conductors It Within range of the pin R2, as it revolves around with the type-wheel. rlhe type-wheel revolves until the arm or pin It strikes the spring R,and presses it against the spring It, thus shortcircuiting the current over line K, around the type-wheel magnets J J, thus destroying their power, and bringing the type-wheel to rest. If desired, the figures and letters on the typewheel might be arranged in one plane alternately, or in any other manner desired, upon a single type-wheel; but I prefer the construction shown, because it prints the figures and letters in different lines, rendering it more easily read.

In place of using polarized magnets J J an ordinary well-known vibrator may be used to rapidly vibrate the armature I; but I prefer to use the polarized electro-magnets and armature, as it makes the instrument more positive.

I do not limit myself' to the construction shown, as my invention may be modified in various ways without departing from my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
